     The function Server.URLEncode converts a inputstring to an URL encoded outputstring. For example: input: Server.URLEncode("part1?part2") output: "part1%3Fpart2" But what if you need the opposite functionality ? There is no function available for this so you have build this yourself. How ? By using regular expressions, of course.
